The annual RC Baja competition which is held at Central Washington University during the third week of April, showcases the different remote-control vehicles built by the student teams and put the vehicles in series of different challenges such as the sprint, slalom, and motocross. The objective of the senior project is to design, manufacture, and test mainly a drivetrain system as well as a chassis. The drivetrain system provides power for the driving force and the chassis provides housing for the different components of the vehicle. The process began with setting requirements for the vehicle that was used to determine the different analysis needed to achieve those requirements. Principles of kinematics were used for determining the maximum speed of the vehicle, strength of materials was used for determining the material stress and strength; lastly, mechanical design was used for designing the drivetrain. The series of different analysis was followed by a series of CAD modeled parts and assemblies on Solidworks that were manufactured by the student team. Therefore, the process ended with the construction of the drivetrain and chassis that were manufactured using machining, 3D printing, and outsourcing parts. As a result, the drivetrain system achieved success in providing the driving force of the vehicle that reached a maximum speed of 56 miles per hour. In addition, the chassis achieved success in providing housings for the drivetrain, suspension, and steering sub-assemblies while weighing under 8 pounds. Therefore, the student team successfully built a functioning RC vehicle.
